Alan McGraw said he first encountered the snake Wednesday while walking his dog outside the Cocoa house he shares with his wife, Erin, and their 16-month-old daughter, WFTV, Orlando, Fla., reported Thursday.
McGraw said the snake slithered under his home and his neighbor's attempts to scare it out with firecrackers failed.
He said trappers arrived on the scene but were unable to reach the snake, despite breaking through concrete underneath the home.
The McGraws said the trappers plan to return next week, but the mysterious disappearance of a neighbor's cat has led them to take extra security measures for their daughter.
"She's basically at grandma's house. I'm going to leave her there until this situation is resolved," Erin McGraw said. "It's very stressful. It's scary."
